mail form validation

ok so somehow my php mail form just broke....and I don' t know why so I want to build it from scratch and learn from it

I need to pass two fields from a form and send it to myself.

I need to validate these two with javascript

one field is email and the other is phone number

if either of these is incorrect there needs to be an errror message

i would like to send html and text version of the email also

i keep trying but somehow it just isn't sending to my email address.

thanks!

 

Can you show us the code?

 

<?php










/* All form fields are automatically passed to the PHP script through the array 
$email = $_GET['email'];
$comments = $_GET['comments'];
$message = "doodie";


/* PHP form validation: the script checks that the Email field contains a valid email address and the Subject field isn't empty. preg_match performs a regular expression match. It's a very powerful PHP function to validate form fields and other strings - see PHP manual for details. */
if (!preg_match("/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/", $email)) {
  echo "<h4>Invalid email address</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
} elseif ($subject == "") {
  echo "<h4>No subject</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
}

/* Sends the mail and outputs the "Thank you" string if the mail is successfully sent, or the error string otherwise. */
elseif (mail($email,$subject,$message)) {
  echo "<h4>Thank you for sending email</h4>";
} else {
  echo "<h4>Can't send email to $email</h4>";
}
?>

Code (markup):

this is what i was trying out.

this was just to see if i could validate it not exactly what i want to do but i am trying to learn.
